KEY MESSAGES
- Seasonally cool and sunny this weekend followed by a warming and continued dry trend for a majority of next week.
SHORT TERM /THROUGH SATURDAY/
Issued at 1200 AM CST Fri Nov 13 2026
A slow-moving upper trough prevails over eastern North America early this morning. This feature consists of multiple closed and almost gyrating circulations over the central to eastern Great Lakes, all making for continued sluggish movement into the weekend. Cyclonic flow from this trough means continued northerly tropospheric flow today over our CWA. Highs should be similar to yesterday with oscillating sun and areas of stratocumulus, and overall less blustery conditions. The sky will clear for good late day into evening meaning seasonably cool lows tonight. A sunny Saturday then awaits!
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Issued at 1200 AM CST Fri Nov 13 2026
A gradual moderation in temperatures will be realized through the first half of next week as the pattern shifts to an upper ridge overhead. This ridge has impressive strength with mid- level heights in the upper couple percentile for the time of year (580 dam). This, along with the blocky pattern, signifies the ridge has staying power. So local area dryness should continue with only a quarter of available NBM members showing showers in the Wednesday night to Thursday time. With midweek moderating afternoon temperatures to around 60 this time of year, we would typically be concerned about a potential fire weather threat (i.e. concurrent gusty southwest winds). However, because of the pattern sluggishness, the pressure gradient is slow to tighten so there is not an immediate signal in our forecast tools for overlapping anomalous winds and warmth.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
Issued at 1200 AM CST Fri Nov 13 2026
Northerly winds will prevail through the TAF period and dance around 360 degrees with regularity. Sporadic gusts in the 15-20 kt window will be seen today before dropping off markedly near sunset. Stratocumulus between 3kft and 4.5kft will vary between scattered and broken.
